Answer:
F = 24
Step-by-step explanation:
Given that F is inversely proportional to d² then the equation relating them is
F= ← k is the constant of proportion
To find k use the condition F = 6 when d = 6 , then
6 = =
( multiply both sides by 36 )
216 = k
F = ← equation of proportion
When d = 3 , then
F = =
= 24

Answer:
Step-by-step explanation:
Surface area = lateral area + 2(area of base)
Lateral area = perimeter of base * height.
Because it is a isosceles right triangle, both sides are equal.
= 72
2 = 72. Divide both sides by 2
= 36. Square both sides.
x = 6.
So the perimeter of the base = 6 + 6 + = 20.485281374239
Lateral area = 20.485281374239 * 7 = 143.397
Area of base is (1/2)base * height.
(1/2)(6)(6) = 18
Using the surface area formula
surface area = 143.397 + 2(18) = 179.4
Answer:
a) MARKUP PERCENT = 200%
b) <u>If the cost price of clothing A = $10</u>
then its retail price = $30
<u> If the cost price of clothing B = $25</u>
then its retail price = $75
Step-by-step explanation:
Let us assume the original price for the clothing = a
Now, boutique triples the price of the items it purchases for resale.
So, the resale value of the item of clothing = 3 times (Original price) = 3 a
So, here: The resale Value = 3 a
a) MARK UP Percentage =
or, the MARKUP PERCENT = 200%
b) Two expressions that represent retail price
<u>If the cost price of clothing A = $10</u>
then its retail price = 200% of 10 + 10 = 20 + 10 = $30
<u>If the cost price of clothing B = $25</u>
then its retail price = 200% of 25 + 25 = 50 + 25 = $75
